Webhalf-life (t 1/2). It is the time required to reduce the original initator content of a solution by 50%, at a given temperature. Assuming first order decomposition kinetics, which is true for most free radical organic initiators, the half-life (t 1/2) is related to the initiator decomposition rate (k d) as follows: t 1/2 = ln2/k d Webhalf-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half. The …
WebThe elimination half-life (t 1/2) is the time required for the amount of drug in the body to decrease by half (eqn [5]). The half-life is independent of the dose of the drug administered and is a useful indicator of how fast a drug is removed from the body.
